OP-7 octylphenol ethoxylate is a nonionic surfactant with relatively stable chemical properties. It is not classified as a flammable liquid and can be stored and transported according to general chemical storage practices. Proper storage methods are crucial for maintaining product performance and effectiveness, with key considerations including temperature control, container airtightness, and protection from light.
Under low-temperature conditions, the product may become cloudy or solidify, which is a normal physical change and not a sign of deterioration. Simply transfer the product to a room-temperature environment to slowly recover, stir evenly, and it can be used normally without affecting product quality. If the shelf life is exceeded, the product must be tested to confirm quality compliance before continued use.
| Storage Factor | Specific Requirement |
|---|---|
| Temperature Range | Recommended 5°C to 35°C, avoid freezing |
| Environmental Requirements | Cool, dry, well-ventilated warehouse; avoid direct sunlight and high-temperature environments |
| Container Requirements | Keep containers sealed to prevent moisture absorption and contamination; use closed containers made of stainless steel, polyethylene, or plastic-lined iron drums |
| Prohibitions | Keep away from heat sources, sparks, open flames, and strong oxidizers; avoid prolonged contact with metal materials such as copper or aluminum |
| Shelf Life | Two years under original sealed packaging and compliant storage conditions |
It is recommended that users prioritize using batches with earlier production dates (first-in, first-out principle) upon receiving the product to avoid long-term accumulation. After each use, immediately seal the container to minimize exposure to air and prevent moisture absorption and contamination. If the product becomes cloudy or separates during low-temperature storage in winter, do not directly heat or use an open flame; instead, place it at room temperature (15-25°C) to naturally warm up and stir evenly.
